Abstract: The disclosure herein describes a client-side system that enhances user experience on a remoting client without consuming additional network bandwidth. During operation, the system receives a sequence of frame updates for a display screen, and determines a sequence of frames corresponding to the frame updates. The system further adaptively applies one or more image enhancing techniques to the sequence of frames based on available network bandwidth, frame refresh rate, or image quality. The image enhancement techniques include predicting a frame based on previously received frames, interpolating a frame based on at least two buffered frames, and reducing appearance of artifacts in a received frame, thereby reducing visual artifacts.

Abstract: Methods, systems, and computer programs are provided for measuring the performance of display images received on a remote computer display. One method includes an operation for detecting calls from an application to an application programming interface (API), which is provided for rendering images on a display image, each call causing an update of the display image. Further, the method includes an operation for embedding data for measuring performance in display frames of the display image based on the detecting. The embedding results in modified displayed frames with respective data for measuring performance. The modified displayed frames are transmitted to a remote client, which results in received modified display frames having respective received data for measuring the performance. In addition, the method includes an operation for calculating the remote display quality for the given application based on the received modified display frames and the respective received data for measuring performance.

Abstract: A processor including instruction support for implementing the Camellia block cipher algorithm may issue, for execution, programmer-selectable instructions from a defined instruction set architecture (ISA). The processor may include a cryptographic unit that may receive instructions for execution. The instructions include one or more Camellia instructions defined within the ISA. In addition, the Camellia instructions may be executable by the cryptographic unit to implement portions of a Camellia cipher that is compliant with Internet Engineering Task Force (IETF) Request For Comments (RFC) 3713. In response to receiving a Camellia F( )-operation instruction defined within the ISA, the cryptographic unit may perform an F( ) operation, as defined by the Camellia cipher, upon a data input operand and a subkey operand, in which the data input operand and subkey operand may be specified by the Camellia F( )-operation instruction.

Abstract: In one embodiment, a server system receives, from a client device configured to remotely access a desktop hosted by the server system, user input directed to the desktop. The server system further identifies a desktop operation to be performed in response to the user input, where the identifying is performed without relying on preconfigured information that indicates what the desktop operation should be, determines when the desktop operation has completed, and adds, upon completion of the desktop operation, one or more markers to the desktop. The server system then transmits an image of the desktop that includes the one or more markers to the client device, thereby signaling the completion of the desktop operation to the client device.

Abstract: A computer-implemented method to facilitate administration of a network of members. Members of a network are provided with access to a shared message stream such that the members of the network are able to monitor messages generated by other members of the network posted to the shared message stream, wherein at least some of the messages are indicative of operational conditions of particular other members which generated the messages. Responsive to a first member of the network identifying a specific operational condition of the first member, the shared message stream is monitored for a message related to the specific operational condition. Provided the shared message stream includes a message related to the specific operational condition identified by the first member, an association of the message with an indication that the first member identifies with the specific operational condition is established, wherein the first member is configured to establish the association.

Abstract: In one embodiment, a method displays images from a remote desktop of a desktop GUI on a client device. The method receives a plurality of image blocks for a frame update of an image of the desktop GUI being displayed on the client device. The remote desktop is being run on a host. The client device determines that one or more missing image blocks have not been received for the frame update and determines if the frame update should be performed without the one or more missing image blocks. If the frame update of the desktop GUI should be performed without the one or more missing image blocks, the client device performs the frame update of the desktop GUI using the plurality of image blocks without using the one or more missing image blocks.

Abstract: One method for managing remote display performance includes operations for embedding pixel data in a file of an application executing on a server, and detecting an open window of a graphical user interface (GUI) associated with the application. The pixel data is used to create a pixel strip in the window, while the GUI is being displayed on a remote display of a remote client. Update information for the GUI being displayed on the remote display is transmitted from the server to the remote client, the update information corresponding to the change in the presentation of the open window on the server. Further, a change in a presentation of the open window is detected, and a pixel strip received at the remote display is identified. A performance metric for the remote display is calculated based on the received pixel strip when compared to the expected values for the pixel strip.

Abstract: Methods, systems, and computer programs are provided for managing remote display performance. One method includes an operation for determining pixel data for a group of macroblocks, each macroblock having a group of pixels. The macroblocks are for embedding in respective video frames of a video stream. The pixel data for each pixel in each macroblock is calculated with a formula based on the frame number of the respective video frame and on the location of the pixel within the macroblock. Farther, the method includes operations for embedding the macroblocks in the respective video frames, and for transmitting the video frames with the embedded macroblocks to a remote client. A performance metric for the transmitted video stream is calculated based on the macroblocks received at the remote client by comparing the received macroblocks to the expected macroblocks based on the formula.

Abstract: The description covers a system and method for operating a micro-processing system having a runahead mode of operation. In one implementation, the method includes providing, for a first portion of code, a runahead correlate. When the first portion of code is encountered by the micro-processing system, a determination is made as to whether the system is operating in the runahead mode. If so, the system branches to the runahead correlate, which is specifically configured to identify and resolve latency events likely to occur when the first portion of code is encountered outside of runahead. Branching out of the first portion of code may also be performed based on a determination that a register is poisoned.

Abstract: Exemplary methods, apparatuses, and systems include a client virtual machine processing a system call for a device driver to instruct a physical device to perform a function and transmitting the system call to an appliance virtual machine to execute the system call.
